MQ135 gas sensor - air quality in general

Gas sensor MQ135 detects the presence of a lot of different gases in the air which is crucial in giving a general quality of air. The best results are given when alcohol is in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly. • Detects: ammonia, sulfides, benzene steam, smoke, other dangerous gases ...

Measuring CO2 with MQ135 – Pocket Science Lab

· The SNS-MQ135 has its own load resistor, which unfortunately is only 1K. Such a small load resistor means the output voltage on AO will be very small when measuring CO 2, which limits measurement accuracy. If possible, you should desolder the built-in SNS-MQ135 load resistor (outlined in red in figure 6), and use an external load resistor as in figure 5 instead. The caveat about the +5V …
